I have a bantam self-blue D'uccle hen that is the friendliest little thing. She's considerably smaller then the vast majority of our mixed flock, so when it came around to feeding time I would always giver her a little something extra (usually kitchen scraps or a tiny bit of starter). After a while she became practically finger-tame and loves to sit in my lap or talk to me.
My buff orps are very friendly too, I used to have one that even as a chick, loved to flop out on you like a little chicken pancake - shame a hawk got her. My remaining Buffs will sit and talk with me, but none are nearly as demonstrative.
Out of the ~10-12 breeds I have, I'd mostly say that breed doesn't seem to play in a huge factor so much as the individual and your bonding experience. If you teach them that you're safe, that you're the provider, they'll realize you're the bee's knees - they'll relax and you can make a stronger bond.
Just my experience anyways.
